You might be asking yourself, what is Avitae? First off, quit talking to yourself — it's kinda weird. Secondly, it would probably make sense for us to start by stating a few things that Avitae is not. It's not a sugary soda. It's not a chemical-pumped energy drink. And it's clearly not a form of boring, breath-killing coffee. Avitae is purified water with natural caffeine acting as a natural energy booster. And for good measure, we tossed zero calories in there too.
